Hi Bogdan,
I know that multicast traffic is flowing but the problem comes with:
"I got the MSDP peer up but it seems that multicast routing table is not exchanged between the two MSDP peer (R4, R5).0"
When you issued "show ip msdp sa", are you able to see sa exchange? your msdp session seem up and running but in fact is not. Due to both routers have configured the same RP address you will have multicast connectivity but not with msdp working properly. If you shut down one router (r6 or r5) the router r6 will found the RP address because the loopback is also published by "the survivor", so multicast will work but msdp not.
Br,
Roberto

An also, note that sometimes msdp is established but not working because the msdp id-originator is loopback by default. So I recommend to you change this source of msdp sessions to interfaces using the command ip msdp id-originator.

The "problem" I mentioned was not that the multicast was not working
- the problem was that it was working better than the SG said it should! :)
[ If the MSDP session is established and working properly, pings can
go from one end of the multicast network just fine. However, the IE SG
says they shouldn't, and we just don't understand why :) ]
